Male Hypogonadism
What is Male Hypogonadism?
Male hypogonadism is a condition where your body doesn't make enough testosterone. Testosterone is the main male sex hormone that controls many important functions. These include muscle mass, bone density, sex drive, sperm production, and mood regulation.
There are two main types of male hypogonadism. Primary hypogonadism means the problem is in your testicles. They can't produce enough testosterone even when your brain sends the right signals. Secondary hypogonadism means the problem is in your brain. Your pituitary gland or hypothalamus doesn't send proper signals to your testicles.
Low testosterone affects about 2 to 6 million men in the United States. It can happen at any age but becomes more common after age 40. Many men lose about 1% of their testosterone each year after age 30. The good news is that this condition can be detected with blood testing and managed with proper care.
Symptoms
- Low sex drive or reduced interest in sexual activity
- Difficulty getting or maintaining erections
- Fatigue and decreased energy levels throughout the day
- Loss of muscle mass and decreased strength
- Increased body fat, especially around the abdomen
- Mood changes including depression, irritability, or difficulty concentrating
- Hot flashes or night sweats
- Decreased bone density leading to brittle bones
- Reduced facial and body hair growth
- Breast tissue development in men, called gynecomastia
- Infertility or low sperm count
Some men with male hypogonadism experience only a few symptoms. Others may notice gradual changes over several years. Symptoms can be mild at first and worsen over time. Many men attribute these changes to normal aging and don't realize they have a treatable condition.

Causes and risk factors
Male hypogonadism can develop from many different causes. Primary causes include undescended testicles at birth, injury to the testicles, mumps infection affecting the testicles, cancer treatments like chemotherapy or radiation, and genetic conditions like Klinefelter syndrome. Aging naturally decreases testosterone production in most men. Certain medications, especially opioid pain relievers and steroids, can interfere with hormone production.
Secondary causes involve problems with your pituitary gland or hypothalamus. These include pituitary tumors or diseases, inflammatory diseases like sarcoidosis or tuberculosis, HIV/AIDS, obesity, and chronic stress. Metabolic conditions like type 2 diabetes and metabolic syndrome significantly increase your risk. Sleep apnea can disrupt hormone production during rest. Heavy alcohol use and drug abuse also damage hormone-producing tissues. In some cases, doctors can't identify a specific cause.
How it's diagnosed
Doctors diagnose male hypogonadism by combining your symptoms with blood test results. A simple blood test measures your total testosterone levels. Testing is most accurate when done in the morning between 7 AM and 10 AM. That's when testosterone levels are naturally highest. Your doctor will likely test your testosterone at least twice to confirm low levels. Normal testosterone ranges from about 300 to 1,000 nanograms per deciliter.
Additional blood tests help identify the underlying cause of low testosterone. Sex Hormone Binding Globulin, or SHBG, is essential for calculating your bioavailable and free testosterone. High SHBG can mask true testosterone deficiency. Low SHBG can indicate metabolic causes of your condition. Prolactin testing is also important because elevated prolactin suppresses hormone signals that control testosterone production. Rite Aid's preventive health testing includes both SHBG and Prolactin measurement. This helps you and your doctor understand your hormone health and identify root causes early.
Treatment options
- Testosterone replacement therapy through injections, gels, patches, or pellets under the skin
- Weight loss through diet and exercise, which can naturally increase testosterone levels
- Strength training and resistance exercises to build muscle mass
- Getting 7 to 9 hours of quality sleep each night
- Managing stress through meditation, yoga, or counseling
- Limiting alcohol consumption to moderate levels
- Treating underlying conditions like sleep apnea or diabetes
- Adjusting medications that may interfere with testosterone production
- Eating a balanced diet rich in healthy fats, protein, and vegetables
- Maintaining healthy vitamin D and zinc levels through diet or supplements
- Medications to treat high prolactin if that's causing your low testosterone
Work with your doctor to find the right treatment approach for your situation. Many men see improvement with lifestyle changes alone. Others need testosterone replacement therapy combined with healthy habits. Regular monitoring with blood tests ensures your treatment is working safely and effectively.

Frequently asked questions
The earliest signs often include decreased sex drive, difficulty with erections, and unexplained fatigue. Many men also notice reduced morning erections or decreased spontaneous erections. Mood changes like irritability or mild depression can appear before physical symptoms. Some men first notice these changes in their 30s or 40s.
The answer depends on the underlying cause. Secondary hypogonadism caused by obesity, medications, or sleep apnea may improve with lifestyle changes or treating the root cause. Primary hypogonadism from testicle damage or genetic conditions is usually permanent. However, testosterone replacement therapy can effectively manage symptoms even when the condition can't be cured.
Normal aging causes gradual testosterone decline of about 1% per year after age 30. Male hypogonadism causes testosterone levels to drop below the normal range, typically under 300 nanograms per deciliter. Men with hypogonadism experience more severe symptoms that significantly impact quality of life. Blood testing is the only way to tell the difference between normal aging and true hypogonadism.
Total testosterone is the primary screening test for male hypogonadism. Sex Hormone Binding Globulin helps calculate your bioavailable and free testosterone for a more accurate picture. Prolactin testing identifies whether elevated prolactin is suppressing your testosterone production. Your doctor may order additional tests like LH, FSH, and estradiol to determine the cause and guide treatment.
Yes, weight loss can significantly increase testosterone in overweight and obese men. Studies show that losing 5 to 10% of body weight can raise testosterone by 50 to 100 points. Visceral fat around your organs produces enzymes that convert testosterone to estrogen. Reducing body fat decreases this conversion and improves your body's natural testosterone production.
Testosterone replacement therapy is generally safe when properly monitored by a doctor. Regular blood tests check your testosterone, red blood cell count, and prostate health. Potential side effects include acne, sleep apnea, and increased red blood cells. Men with a history of prostate cancer or severe heart failure should not use testosterone therapy.
Yes, male hypogonadism can cause infertility by reducing sperm production. Low testosterone means fewer sperm cells mature properly. Some men with hypogonadism produce no sperm at all. If you want to have children, tell your doctor before starting testosterone replacement therapy because it can further reduce sperm production.
Chronic stress can lower testosterone by increasing cortisol levels. Cortisol is your stress hormone, and it interferes with testosterone production. High cortisol also increases abdominal fat, which converts testosterone to estrogen. Managing stress through exercise, sleep, and relaxation techniques can help protect your testosterone levels.
SHBG is a protein that binds to testosterone in your blood. Only testosterone that's not bound to SHBG can enter your cells and work properly. High SHBG levels can make your total testosterone look normal when your active testosterone is actually low. Low SHBG often indicates metabolic problems like insulin resistance that contribute to hypogonadism.
If you have symptoms of low testosterone, get tested at least twice to confirm the diagnosis. Once you start treatment, your doctor will typically retest after 3 to 6 months to check effectiveness. After stabilization, annual testing is common for monitoring. Men over 40 with risk factors may benefit from checking testosterone levels every 1 to 2 years even without symptoms.
